AP62500 4.5V TO 18V INPUT, 5A SYNCHRONOUS BUCK CONVERTER Description The DIODESTM AP62500 is a 5A, synchronous buck converter with a wide input voltage range of 4.5V to 18V. The device fully integrates a 47mΩ high-side power MOSFET and an 18mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. The AP62500 device is easily used by minimizing the external component count due to its adoption of Constant On-Time (COT) control to achieve fast transient response, easy loop stabilization, and low output voltage ripple. The AP62500 design is optimized for Electromagnetic Interference (EMI) reduction.
